Calculator Secret Vault — keep your private photos and files truly private.

Calculator Secret Vault is a secure, on-device vault for the photos and files you don't want anyone else to see. Everything you store is encrypted with AES-256 and stays on your phone — no cloud, no accounts, no tracking, no ads.

A vault hidden in plain sight
Calculator Secret Vault opens as a fully working calculator. Enter your secret code and press "=" to reveal your private vault. To anyone else, it's just a calculator.

Strong, real encryption

Every photo and file is encrypted with AES-256 before it's saved.
Your master password is never stored — the key is derived from it each time you unlock.
Even the file names are encrypted, so nothing about your content is exposed.

Key features

🔒 Encrypted vault for photos and any file type
🧮 Calculator disguise with a secret unlock code
📁 Organize items into folders (drag and drop to move them)
👆 Optional fingerprint / face unlock
♻️ Move photos back to your gallery, or files to Downloads, anytime
🖼️ Import several photos at once — with the option to remove the originals
🔑 A recovery code so you're never locked out
🕵️ Intruder capture: if someone enters the wrong password, the app can quietly take a photo and note the location, saved encrypted in your vault

Private by design

All data is processed and stored only on your device.
Nothing is uploaded or shared. No ads. No analytics.
Camera and location are used only for the optional intruder-capture feature, and only after you allow them.

Permissions

Camera — only for optional intruder capture
Location — only to tag intruder photos, if you enable it
Photos/Files — so you can choose what to move into the vault
Biometrics — optional, for fingerprint/face unlock

Important
Your security is in your hands. Because your files are encrypted with a key derived from your master password, no one — not even us — can recover your data if you forget both your master password and your recovery code. Please keep them safe.
